The are 4 glands in the endocrine system. The thyroid gland, pineal gland, parathyroid gland, and the pituitary gland.
Answer:
-use PCR to amplify the gene for GFP
-perform a restriction digestion of the GFP gene and the plasmid
-ligate together the GFP gene and the plasmid to generate a recombinant plasmid
-transform bacteria with the recombinant plasmid using electroporation
-plate the bacterial cells, and screen for positive transformants
Answer:
Stomata - specialized cells that contract and expand to open or close pores for gas exchange. Stomata can adjust to temperature, staying closed when temperatures are hot and dry to prevent gas and water loss.
Explanation:
Stomata (singular stoma) are pores found in the epidermis of plant leaves. Stomata open and close in response to the change in structure of two guard cells either side of the pore opening. When the guard cells are turgid, the stomata open, when they are flaccid, they are closed.
This functions to permit gas exchange while preventing the loss of water, especially during hot, dry weather. The stomata can only open when the guard cells are turgid, pulling the stomata apart.
These molecules - proteins, lipids, carbohydrates, and nucleic acids - make up every component in living things. Lipids are used as energy and form making membranes that all living things have. Carbohydrates are the primary source of energy for many living things. Proteins are used to build tissues or enzymes. Nucleic acids are used for the genetic material to be transferred to offspring.

Answer:
Replication of the DNA occurs during the S phase of interphase. !!!
Explanation:
Interphase is essentially the first and longest phase of the cell cycle characterized by three distinct phases: growth phase 1 (G1), synthesis (S) phase, and srowth phase 2 (G2).
